Navigation

Your user can navigate through your gallery by simply pressing the left/right buttons or on mobile also by swiping to left or right.

fnx-gallery element

fnx_gallery package contains <fnx-gallery> element. It's a simple position: fixed; element which you can use as a gallery.

Specify dependency in pubspec.yaml:

dependencies:
fnx_gallery: ^0.0.7

Run pub get and in your "index.dart" (or whatever is the name of your main script):

import 'package:fnx_gallery/fnx_gallery.dart';

Closing the gallery

We recommended to use *ngIf to show and hide the gallery. <fnx-gallery> emits (close) event, which indicates
that the user clicked on the close button (or pressed ESC key etc.). Hide the gallery after this event.
